あった。そのため、アモルファス鉄心の特長である鉄心
損失の低減が期待できないという欠点があった。In the past, there have been almost no examples of wound cores using amorphous (non-crystalline metal) being manufactured, and experimentally the only way to wind an amorphous core around a winding core was to put it into an annealing furnace to remove processing distortion. Therefore, there was a drawback that reduction in core loss, which is a feature of an amorphous core, could not be expected.

たことが判る。In the figure, (1) is an amorphous wound core, (2) is a winding core with an approximately U-shaped outer shape having a recess (2a) and a mounting hole (2b), and a sheet-shaped amorphous core (2) is a winding core. It is wound onto a shaft and finished to a predetermined thickness, but processing distortion occurs due to the winding process, and if left as is, it is difficult to ensure a product with stable magnetic properties as well as the shape of the iron core. Can not. FIG. 3 is an explanatory diagram showing the state of annealing performed for removing processing distortion and stabilizing magnetic properties. In the figure, (3) is the fourth part (2a) of the winding core (2) in order to impart alternating magnetic flux (#) to the amorphous winding core (1).
It is an excitation coil wound around an amorphous core (1) using an amorphous iron core (1), and is connected to an alternating current power supply (4). (5)
is a thermocouple whose temperature sensing part is embedded in the mounting hole (2b) of the winding core (2), and whose output part is connected to a temperature controller (6) to control the annealing temperature in the annealing furnace (not shown). used. and,
The amorphous wound core (1) is heated to a predetermined temperature sufficient to remove processing distortion and annealed. At the same time, an alternating magnetic flux equivalent to the alternating magnetic flux actually applied during production is applied via an excitation coil (3). Alternating magnetic flux (IJ) is amorphous wound core (1)
be granted to Figure 4 shows the core material when the alternating magnetic flux (#) is annealed with the magnetic flux density set to 3400 Gauss, which corresponds to the rated voltage of the transformer, and the frequency set to 400 H2, which is the rated frequency of the transformer. The results of actual measurements of the core loss characteristics after annealing are shown in comparison with the results of the annealing.As is clear from the figure, the core loss at the rated magnetic flux density and frequency is approximately 0.24 W in the material due to the treatment by the above method. /
It can be seen that the power consumption was significantly reduced from 0.1 W/kg to 0.1 W/kg after annealing.
